Finish this statement/phrase: "What does a constant slope mean in a velocity-time graph? Slope means acceleration. Therefore, if we have a constant slope, we have a constant ______." (1)...

The area of an acceleration-time graph is: (1) time (2) velocity (3) acceleration (4) displacement

the area of a velocity-time graph is: (1) velocity (2) acceleration (3) displacement (4) time

Constant velocity is represented in a velocity-time graph by: (1) a horizontal line with no slope (2) a curve (3) a line of constant slope

when velocity and acceleration are in the opposite direction, the motion is: (1) slowing down (2) speeding up (3) remaining the same
